I naoonnn I Application filed Kay 18, 1928. Serial No. 278,855,

for its object to provide a heating unit fora brooder, having novel andimproved features of construction. 7

5 Another object of my invention is to provide a combined heating unitand forced draft ventilating system for the brooder.

The stove of m invention is one which may be converts to the t vpecommonly wherein the fuel isallowed to drip from a height through avertical pipe, which comprises the air inlet onto a vaporizing device,from whence the draft carries it in a horizontal lane through a twistingpassageway, in whic it is burned.

Another object of my invention is to provide a heating unit forabrooder, which combines, with the advantages of the winding passageway tofroil burning stove, the

utmost simplicity, durability and cheapness of construction.

More specifically referring to the last object, it is my intention toconstruct a stove Iofthe type mentioned entirely of pipe or B5 tubing,which may be of'the same diameter throughout.

, Another object is to provide with such a 'stove simple and novel meansfor supporting the stove, said means being adjustable as to V height. IV

, Another object is to provide a combined heating unit and forced draftventilator, together with sim 1e and novel means for controlling the drato the ventilator.

' Another object is to provide novel means for supporting a fuel tankupon the upper end of the feed tube of the stove.

With these and other objects in view, my

invention consists in the A construction, arrangement and combination ofthe various parts of my device, whereby the objects contemplated areattained,-as hereinafter more fully set forth, pointed out in my claims,and illustrated in the accompanying drawings, in which:

Fig. 1 is a section-a1 view taken through the center of a brooderinvolving my invention.

2 is a plan view of the stove detached from the brooder.

Fig. '3 is a perspective view of one of the supporting legs of thestove.-

ig. 4 is an enlarged, detail, sectional view through the lower portionof the air inlet flue of the stove.

Fig. 5 is a sectional view through the upper end ofthe air inlet flueillustrating the fuel tank WhlCll is employed when,the drip system isused.

In Fig. 1, I have illustrated a conventional form of brooder having theside walls 10 and ilge roof 11 and having at its top a ventilatorOrdinarily the air from the brooder simply passes through anopening inthe roof below the ventilator and thence into the atmos here.

y invention aims to utilize the stack 13 of the brooder stove for thepurpose of creatmg a forced draft to the ventilator 12.

To this end, the stack 13 is surrounded by asleeve 14, concentricallyspaced from the flue 13 and suitably supported in the ventilatlonopening in the roof 11. The ventilator 12 1s supported by means of arms15 upon the upper end of the sleeve 14.

The stack 13 might-be formed as an integral continuation of the chimney16 of the stove, or it may be constructed separately and fittedthereover, as shown in Fig. '1.

Upon the chimney 16 is slidably supported 7 a damper 17, which, whenraised to the level of the lower end of the sleeve 14, will completelyshut off circulation of air there through and which will vary the draftthrough the sleeve in proportion to its height.

A set screw or the like 18 may be used for 21, 22, 23.and 24:, joinedtogether toform an S shaped construction, the ends of which are joinedrespectively to the chimney 16 and the inlet flue 19.

A diagonal brace 25 connects the pipes 16 and 19 and forms a rigidstructure of the winding series of pipes.

There are several advantages in the construction just described over theold type of construction of drip feed burner, (which ,comprised arectangular box, partitioned of to form a winding passage), one of theseadvantages being the simplicity of construction which is obtained by theuse of uniform pipe sections joined together to form the Winding.passageway. Another advantage resides in a marked increase in heatradiation in the present construction as compared with the inclosedbox-like structure of prior devices.

Another advantage in the present construction resides in the possibilityof'attachment to the vertical pipes 16 and 19 of a pair of supportinglegs, which may be adjusted relative to those pipes, without interferingwith the intervening passageway portion of the stove. By slidinglyattaching the legs directly to the pipes 16 and 19, a verticallyadjustable supporting structure of the utmost simplicity maybe obtained.Y

The desirability of vertical adjustment of the stove has been recognizedprior to my invention. The advantage of the feature resides in theability to adjust the intensity of heat radiation. from the stove to thechicks below the stove.

In this respect, it will be understood that in the most approved formsof chick hovers,

' not onl the. hm er, but the stove itself should be pre erabiadjustable as to height from the floor of t e brooder.

The supporting structure comprises two independent legs, each having achannel shaped base 26, a pair of uprights 27 and 28, connected at theirlower ends to the base 26 and secured at their upper ends to a splitring 29, adapted to encircle and clamp each of the upright pipes 16 and19. A tightening bolt 30, which may be a thumb nut or the like, clampsthe ring 29 against its respec-' tive pipe.

'It will now 19, respectively, are received between the uprights 27 and28,and that the stove may be lowered until the'horizontal pipes 20 and24 rest upon the upper edges of the channels 26. Thus at no time willthe stove be allowed to come into contact with the floor of the brooderand the danger of fires will thus be minimized.

It will be noted from an inspection of Fig. 2 that the supporting legswill be secured to their respective pipes so as to extend parallel toand underneath the pipe portions 21 and 23, overlapping each othersomewhat and extending sufficiently on either side of the center linejoining the axes of the pipes 16 and 19 to insure against tipping of thestove.

The upright 28 may be bracedby means of a diagonal brace 31.

The hover 32 is supported upon the pipes be noted that the pipes 16 and(See Figs. 1 and 4.) Vhere the stove is used as a tank heater, the dripsystem is employed and I provide a readily attachable and de. tachablefuel tank, as shown in Fig. 5.

The fuel tank 34 has secured to its bottom a depending annular collar35, to which are Socured inwardl extending fingers 36, provided with hoos 37, adapted to hook ovr the edge of the pipe 19 in order to supportthe tank thereon in coaxial relation therewith. The collar 35 overlapsthe upper end of the pipe 19 so as to guard against sudden draftsaffecting the smooth flow of air currents therethrough.

The drip valve which is of an old construction is shown at 38. The fuelis allowed to drip from the valve 38 upon a mass of ashes 39 in thelower end'of the air flue 19. This element is old and does not form apart of my invention. The oil is vaporized as it strikes against theashes, which are heated by conduction of the heat from the portion ofthe stove where burning takes place through the walls of the stove.

Nhere the feed. shown in Fig. 1, is used, the oil works its way upthrough the mass of ashes by capillary action and is vaporized duringthe process. Combustion commences in the pipe 24 and continues throughthe pipes 23, 22, 21 and 20.

It may now be noted that the air within the sleeve 14 will be heated toa higher degree than the air surrounding thesleeve 14 and.

the general atmosphere within the brooder and consequently a column ofair which is lighter than the remainder of the air within the brooderwill be formed. Thiscolumn of air will ascend, due to its levity andwill create a forced draft within the brooder. Creation of this forceddraft is accomplished by heat, which would otherwise go up the chimneyin the form of waste heat.

The sleeve 14 serves not only to segregate a column of air forsuper-heating and forced draft but also servesto hold the heat Withinthe brooder. Instead of having a directavenue of escape through anopening in the roof, the heated air must enter the sleeve at its lowerend in order to escape. 'Thus all of the heated air above the lower endof the sleeve is trapped. .In actual o eration the heated air andgases-ascend to t e upper region of the building and then traveldownwardly around the sleeve 14, after havin cooled slightly. Acontinuous circulation of air throughout the entire building is thusassured. v 7

Some changes may be made in the construction and arrangement of theparts of my invention without departing from the real spirit and purposeof my invention, and it is my intention to cover by my claims, anymodified forms of structure or use of mechanical equivalents, which maybe reasonably included within their. scope.
